| I think a solution to the small-size sound would be to size the output allpasses not linearly with the loop size, but in some other relationship 'tweaked' to get the sound right. It sounds close, but not quite right. A table lookup and interpolate is trivial, so making them nonlinear is easy.
Above 10 metres (about 6k of memory used), it is fine. Above 20 metres it sounds quite good. That is a 5:1 range of sizes for one algorithm, that has about the same ratio limits as the PCM70's plate and chamber algorithm size range (they go from around five metres to around thirty). It is possible that changing the output taps around at a small size might make it sound better smaller, and then it should sound good when sized up. Do you ever find the need to shift the output taps any way but linearly with size? Also, is there any reason to increase the number of taps on this algorithm? Is that something to experiment with? Or do you have another 'next thing to do' that's even better?
